DOOR HOLDER Filed Raw. 10. 1927 Patented Mar. 11, 1930 CHARLES COMSTOCK,NEW HYDE PARK, NEW YORK DOOR HOLDER Application filed November 10',1927. Serial No. 232,292.

My invention relates to mechanism for holding a door open or partly openand is particularly adapted for constructions, such as garage doors. Themain object is to provide a simple but reliable mechanism for thispurpose which can be easily installed.

Another object is to provide a construction of this character which isinexpensive and readily operated.

In its preferred form the invention consists of three main parts,namely, a metal channel adapted to be secured to the door, a swingingarm carried by the door frame and co-ac'ting with the channel and'areleasing lever carried by the" door. The detailsof the preferred formWillbe understoodffrom 'inspection of the accompanying single sheet/ofdrawings and the following specification:

' Fig. 1 is a perspective view of apparatus embodying my inventionshowing the doors open.

4 Fig. 2 is a fragmentary face view showing the parts in their co-actingrelation when the door is closed. v v Fig. 3 is a fragmentary large viewshowng the parts in the interlock, that is the pen door position.

Fig. 4. is a Vertical. transverse sectional view., i 1 V ig. 5, is adetailed view of one end of the channel.

The channel 6 is preferably formed of sheet steel or. iron and suitablysecured to the door 7. The arm 8 is pivotally secured to the undersideof the door frame 9. The

release lever .10 is hinged to the door. The door is hinged to the frameat the point 11. I have also shown a door 7 located adjacent the door?asis sometimes done in whatis called a double door construction.

The channel 6 is secured to the door by two or more screws 12 which passthrough a ,vertical web of the channel 6. The channel also has a bottomwall 13 adapted to supportth'e movable end of the arm 8 and it also hasa vertical flange 14 and a horizontal top flange ,The arm 8 is hingedSor pivoted on the screwor bolt 16 beneath the reinforcing and bearingplate 17. The outer end of the arm 8 is provided with a downwardlyextending hook-like member 18 adapted to slideon the flange 13 andinside of the flange 14:. The top flange 15 is spaced apart from theupper edge of the flange 14 a distance suflicient to allow for thetravel of the arm 8. The bottom flange 13 is provided with an opening 19into which the end 18 of the arm 8 drops when the door is opened to therequired extent. The flange 14 is cut away at 20 to allow for thedropping of the arm 8 at the position shown in Figs. 1 and 3. One edgeof the opening 19 is inclined at 21 and the lower end of the hook 18 isrounded off or bevelled at 22 so as to facilitate the disengagement ofthe hook 18 from the hole 19. A stop screw 23 is also preferablyprovided to prevent the hook 18 from accidentally sliding out of the endof the channel 6 when the door is being opened.

a The release lever 10 is pivoted on the pivot 25 which is carried by anarm of the bracket 26 which is secured by the screw 27. The end of thelever 10 beneath the tip of the hook 18 is provided with an off set 28adapted to engage the tip of the hook 18 so as to lift the hook out ofthe hole 19 when the chain 29 is pulled. The spring 30 is secured to theshort arm of the lever 10 and is secured to the door by means of ananchor member 31 which in turn is secured to the door byscrew 32 and apoint or lug 33. The upper end of the anchor member is provided with anoff set portion 34 so as to keep the spring away from the door.

When the door is closed as shown in Fig. 2, the holder has no effectupon it and the door can be latched, locked or hooked in any suitablemanner When it is desired to open the door it is swung in the usualmanner during which movement the tip 18 of the arm 8 slides along thechannel 6 until, when the door is opened to the required extent, thehook 18 falls into the hole 19 and locks the door against furthermovement. When it is desired to close the door it is simply necessary topull on the chain or cord 29 and lift the tip of the holder 8 out of thesocket 19, whereupon the door can be closed without interference fromthe doorholder.

top flange serving channel formed by It should be understood, of course,that the bevelled tip 22 and the incline 21 facilitate the closingmovement as soon asthe incline 21 tends to lift the bevelled tip 22 aspressureis applied on the door to close it. Ordinarily, however, whenthe spring is pulling the left hand end of the lever 10 downwardly thehookportion 1 8 of the arm 8 tends to prevent accidental movement of thedoor.

The angle at which the door will stand when opened to its limit withthis apparatus depends upon the position at which the channel 6 islocated on the door and also the tance of the screw 16 from the verticalaxis of the hinge 11.
